Conditions for famous water

"Making water" activates the water that has passed through the device to the level of spring water, which is considered to be one of Japan's most famous waters.
Then, how should we judge that it is "famous water"?

Here, we will explain while comparing the components based on the "conditions for famous water" defined by the Japan Groundwater Society.

Conditions for famous water

According to the Japan Groundwater Society, the conditions for famous water are judged by the following six components contained in the water.

・ Sulfate ion ・ Bicarbonate ion ・ Chloride ion + nitrate ion ・ Magnesium + iron ・ Calcium ・ Sodium + potassium

When these ingredients are displayed in mg / L on a stiff diagram, it is defined that the ideal water is a rhombus or abacus ball .

What is the Japan Groundwater Society?

Established in 1959. Conducted more than 100 famous water surveys all over Japan.
The number of members is 1,000, and it has researchers and engineers in a wide range of fields such as science, engineering, and agriculture related to groundwater. It has research and technology related to the development of comprehensive academic studies on groundwater and the development and conservation of groundwater. An academic society aimed at widespread dissemination. (Quoted from the website of the Japan Groundwater Society)
Presented "Science of Famous Water" in 1994 and "Conditions for Famous Water" in 1999.

Comparison of natural water and tap water

Based on this evaluation standard, the table below shows the results of comparing natural water, which is a well-known spring water, with urban tap water.
The "ideal natural water" on the right side of the table has a diamond-shaped or abacus-shaped diagram.

On the left side of the table, "Currently urban tap water", you can see that the shape of the diagram is broken.

City tap water: The collection method is 3 times, divided into 3 days. Our own survey.

[Discussion]
・ Increase in sulfate ions → It is presumed that this is due to the exhaust gas from petroleum fuels.

・ Increase in nitrate ions → It is presumed that this is due to untreated waste of livestock manure, pesticides, and domestic wastewater.

・ Increase in chloride ions → It is presumed that this is due to chlorine contained in tap water for disinfection.

* The above is our own consideration for the collected data.

Comparison of tap water and passing water

The following is a comparison between tap water and "water-making" passing water (here referred to as MZ treated water or RS reactor treated water). Compared to tap water, the passing water of MZ treated water has a stiff diagram closer to the abacus ball shape.
